1.What is the difference between Page-Validate and Property-Validate methods?
Page-Validate method is used to validate all the properties present
on a page. If a page has embedded pages, this method works recursively
to validate all the properties. This method consumes lot of system
resources and takes more time. If you want to validate specific
properties use Obj-Validate method with Rule-Obj-Validate rule.
Property-Validate method is used to impose restrictions on a property
value. Use Edit validate rule along with Property-Validate method to
impose restrictions. You can validate multiple properties using
Property-Validate method.
2.What is difference between Edit validate and Edit Input rules?
Edit Validate : Use edit validate rule to validate the property value
using java code. Edit validate rules can be used property-validate,
Rule-Obj-Validate and Property rules.
Edit Input : Edit input rules converts user entered data into
required format. For example is the user enters date MM/DD/YYYY format,
edit input rule coverts this date into DD-MMM-YYYY (required format).
Again we need to write java code for this transformation.
3.Where assignments will be stored in pega rules database?
Work List related assignments are stored in pc_assign_worklist.
Work basket related assignments are stored in pc_assign_workbasket.
4.Where work objects will be stored ?
Work Objects are stored in pc_work table by default. however if you
want to store the work objects in a user created table, follow the below
mentioned steps.
Create a schema similar to pc_work table. (The best thing is to copy
the pc_work schema and modify the table name and constraints name if
any)
Change the class group mapping (Data-Admin-DB-Table) to the newly created table.
5.If I have 3 different work objects in my application, how to store them in three different tables?
Open/Create the Data-Admin-DB-Table instance for each class and
mention the table name. By doing this the individual work objects will
be stored in the new table you mentioned in the Data-Admin-DB-Table
instance. This is a best practice if there too many object instances for
each class.
6.What is StepStatusGood, StepStatusFail rules?
StepStatusGood is a when condition defined in @baseclass, this when
rule checks whether the value of pxMethodStatus property is "Good".
StepStatusFail is a when condition defined in @baseclass, this when
rule checks whether the value of pxMethodStatus property is "Fail".
7. How to make any rule as a favorite to your manager
Delegate the rule to manager.
8. Where can i see the paramater values in the clipboard ( values ..) i am passing one activity to other .
No its not possible in clipboard, but you can see in tracer by clicking page name which in step method column .
9. How to import rules using pzinskey
Open the rule, from that pick the pzinskey, go to prdbutil and
using the pxinskey export the rule Import that zip file where you want.
10. Difference between activity and utility
An activity is an instance of the Rule-Obj-Activity rule type. An
activity is the fundamental sequential processing unit of the Process
Commander system.
The shape in a Visio flow diagram, references an activity that updates a work object, but does not require user interaction and input. Your system includes standard activities for utility tasks, and you can create additional ones.
Each utility task references an activity with an Activity Type of Utility ss from utility shape we can call activity but vise versa not possible.
11. Difference between obj-open and obj-open-by-handled
Obj-Open : we will get multiple records from table based on the
criteria from the specified class. Or Opens an instance of a given
class
OBJ-open-handle: here we have have to pass the pzInskey as a instance handle, this mehod will open only one record at time. Or Open object by handle to the pzInsKey value
The handle of an instance is a unique key, in an internal format,
assembled by the system that identifies an instance in the PegaRULES
database. It may differ from the visible key generally used to identify
instances. (Every instance has a unique handle, but more than one
instance may share the same visible key.) For rule instances, the handle
includes system-generated identifying values (including the create date
and time) that make it unique.
Use the Obj-Open-By-Handle method only if you can determine the unique handle that permanently identifies which instance to open. Otherwise, use the Obj-Open method.
12. Inheritance concept in the pega (rules, class)
Rules: inheritance that can maximize reuse of your rules while
allowing localized overriding as appropriate. Also called polymorphism,
inheritance allows a rule created for one class (possibly an abstract
class) to be applied to other classes that inherit from it.
Class inheritance searches for rules from a concrete, lower class, up the class hierarchy to find available rules.
Two types of class inheritance — directed inheritance and pattern inheritances
13. Performance of our work in the pega is measured using?
1. DBTrace: DBTrace is a feature in the Performance Analysis Tool
(PAL) that creates a detailed log of calls to the PegaRULES database.
DBTrace displays SQL statements sent to the database and the time spent
for each operation.
PAL: This data is stored in “PAL counters” or “PAL readings.” PAL stands for Performance AnaLyzer, and is a collection of counters and timer readings, stored in the requestor, that an application developer could use to analyze performance issues in a system.
PAL Features
• Add Reading
• Add Reading with Clipboard Size
• Reset Data
• Save Data
• Start DBTrace
• DBTrace Options
• Start Profiler
• Show Graph
• My Alerts
Alerts:
During application processing, Process Commander writes to the
performance alert log a sequence of text entries called alert messages
that identify mainly performance-related issues or errors. The
performance alert log is usually named PegaRULES-ALERT-YYYY-MMM-DD log.
AES:
Exceptions are processed in a similar way as alerts. When a Process
Commander server generates exceptions they are sent by SOAP to the AES
system. The system parses the exceptions and stores the records in the
pegaam_exception table in the AES database. Based upon how often an
exception occurs and the system events that triggered those exceptions,
AES aggregates these records into work objects called AES exception
items. These items are written to the AES database in the
pegaam_exception_work table.
14. How to connect to different pega applications?
Using SOAP, HTTP, JMS, MQ.
15. How to store the instance of the class in a specific database
Creating the separate DB table for that work class with in the DB, or map to external db and further saves will go to that DB
16. Difference between obj-list, rdb-list?
Obj-list : Retrieve to a page, read-only, a selected set of properties Import ant fields Obj-List:
RequestType: The Type of the browse; allows different processing or sets of properties to be defined. Defaults to Standard. Key-part to the Rule-RDB-SQL instance.
Access: An indication of the database package used to access this table, from the INI file (currently ODBC). Key-part to the Rule-RDB-SQL instance.
ClassName: The object class on which the browse is performed.
Rdb-list: To Retrive external Relational Database List.
Import tant fields in RDB-List:
PageName: Page Name indicating where the results will be put
ObjClass: The object Class to List. When used with RuleObjList parameter, this is the class of the list to use.
17. How to see values of the local variables of the activity.
Using log-message.
18. how can i store the instance of the class in the data base
Creating the separate DB table for that work class with in the DB, or map to external db and further saves will go to that DB.
19. default data table where the instance of the class are store (how it will search ) pc_work
PC_ work
1. Workbasket assignments are stored in a single pr_assign_workbasket table.
2. Worklist assignments are stored in a single pr_assign_worklist table.
3. The Work- base class is mapped to the pc_work table, a table
with columns that represent all the work object properties that need to
be exposed for flow processing to function correctly. Map your work
object classes to either the pc_work stable or another table that has
the same columns.
4. The Data- base class is mapped to the pr_data table. Map your
data classes to either the pr_data table or another table that has the
same columns.
5. all Rule related data will be stored in pr4_pegarules.
6. The pr_other table is the last resort or default destination
for saved insstances that belong to a class that is not mapped to any
other tables.
20. In Routing activity what is the default property used to route the object
pxRouteTo=Param.AssignTo =” work basket name” for work basket .s
For work list:
pxRouteTo =Param.Worklist=”true” && Param.AssignTo =” pxRequestor.pyUserIdentifier” for work list.
21. In routing activity if i use workbasket name instead of work list name .. when can i know it is wrong (run time, complile time)
Run time.
22. Notify
When you want to configure your flow to automatically send
notification messages about assignments, connect a notify shape to the
assignment. A notify shape identifies a notify activity.
23. ticket: explain any senarion u used
Use the Ticket shape ( ) to mark the starting point for exceptions
that may arise at any point in the flow, such as a cancellation. The
ticket is a label for a point in a flow, much like a programming “GOTO”
destination.
24. table used for add note
pc_data_workattach.
25. Default activity used to create work object
There is more than one like Add, CreateWork, and New.
26. Different type of flows. Explain in scenario based where u used and worked
Spin-off, Split- Join and Split for each.
27. work object ID.. how to create.. activites ued to create, or methods Work ID:
Work ID:
RULE-OBJ-ACTIVITY WORK- GENERATEID for Generates Work ID, The
activity checks for the ID of the work object. If the ID doesn’t exist
it gets a unique ID from the database and adds the History.
Create work object:
work objects can be created using Add, AddWork,New…
RULE-OBJ-ACTIVITY WORK- ADDWORK: Call this activity to create a new
work object from a Utility or Post-Processing activity. Prior to
calling this activity create and populate a new work object page using
createWorkPage then use it as the primary page to call this activity.
Caller must commit changes using commitWithErrorHandling.
28. how to send multiple correspondences at a time
Preflight:
Starts the Application Preflight tool, which reports warning
conditions on the rules in your Application RuleSets. These may indicate
guardrail compliance issues, potential performance issues,
accessibility status, or other notable conditions.
- Application Preflight tool to list each rule in an application that contains a warning message. Warning messages suggest that the rule is at variance with guardrails and other best practices. You can also check for browser compatibility of visual elements.
you can extend the set of warnings with a custom activity named
Rule-ZZZZ.CheckForCustomWarnings, where Rule-ZZZZ is a rule type.
Warnings are maintained as instances of the Index-Warning class and saved in the pr_index_warnings database table.
The standard decision tree rule Embed-Warning.pxWarningDetails controls whether warnings of a specific type are reported in the Application Preflight tool. By default, all are reported; you can override this decision tree rule to choose which to omit. This decision tree tests the property pxWarningType, which can have values indicating the source of the warning, such as:
=> Java — an activity contains a Java step
=> API 02 — an activity uses the Version 3 PublicAPI
=> WriteNow — An activity step includes a method with an immediate database write operation rather than a Commit method.
29. How to call an Activity from Java Script?
<Script>
Function A ()
{
var urlPath = “./PRServlet” ;
var url = urlPath + “?pyActivity=GHC-HPlan-CS-Work.ABC&CSR=” + CSR;
window.open(urlPath,”_self”);
}
</script>
30. how to end the workobject in the activity ( method used to kill the work object)
Using java script.
31. how to call an activity from the java, java script
<Script>s
Function A ()
{
var urlPath = “./PRServlet” ;
var url = urlPath + “?pyActivity=GHC-HPlan-CS-Work.ABC&CSR=” + CSR;
window.open(urlPath,”_self”);
}
</script>
Or you can use osafeURL to call an activity
Using java :
sHashStringMap activityKeys = new HashStringMap();
activityKeys.putString(“pxObjClass”, “Rule-Obj-Activity”);
activityKeys.putString(“pyClassName”, workclass);
activityKeys.putString(“pyActivityName”, “HistoryAndAttachments” );
tools.doActivity(activityKeys , workpage, tools.getParameterPage() );
32. How to pass parameters to the activity using the java, JavaScript?
pyActivity=GHC-HPlan-CS-Work.ABC&CSR=” + CSR.
33. How can I pass page as the parameter to the activity using java, JavaScript?
Using java you can, may be using java scripts you can , I not sure
34. How to call an Activity from Java step?
HashStringMap activityKeys = new HashStringMap();
activityKeys.putString(“pxObjClass”, “Rule-Obj-Activity”);
activityKeys.putString(“pyClassName”, workclass);
activityKeys.putString(“pyActivityName”, “HistoryAndAttachments” );
tools.doActivity(activityKeys , workpage, tools.getParameterPage() );
35. How to get a property value from clipboard using Java step?
ClipboardPage workpage = tools.findPage(pagename);
String propername = workpage.getProperty(“.pxResults.Risk”).toString();
Or
String propertyname= tools.findPage(“WorkListPage”).getProperty(“.pxResults.Risk”).toString();
36. How to restrict the harness, section to particular user
Using the circumstances or using different access groups and privileges
37. List different functions used to call an activity from java script.
window.open (urlToRun,”_self”);
openUrlInSpace (urlToRun,”");
Where urlToRun refer the activity name
38. How a user’s ruleset list is formed ( the logic )?
The system adds entries it finds from following sources in the order
listed. The system adds entries it finds from these sources in the top
of the list,
1. Requestor : (Data-Admin-Requestor class) — Usually this adds the RuleSets named Pega-RULES, and Pega-IntSvcs and a version or version prefix for these
2. Division — As referenced in the Operator-ID instance
3. Organization — As referenced in the Operator-ID instance
4. Access Group : As referenced in the Operator-ID instance
5. Ruleset Versions — Prerequisite RuleSets and Versions to those already compiled
6. Operator ID : If this user has the ability to check out rules, the
personal RuleSet (named the same as the Operator ID key) is added last.
Also called as private ruleset.
39. How to connect external java application without using connect-java
SOAP or JMS or IAC s
40. Spinoff // split join explain
Spin-off shape ( ) onto the flow
When a work object advancing through a flow reaches the Spin-off
shape, Process Commander starts execution of a different flow, using the
current or a different work object. Processing in the current flow rule
continues in parallel, without waiting for the other flow to complete.
the Split/Join shape ( ) onto the flow
Use the Split-Join shape to require that multiple subflows of your
flow be completed before the current flow continues execution. This
allows subflows to execute asynchronously, in parallel. For an example,
see the standard flow Work-.ParallelWork.
Split-ForEach shape ( ) to any locations
The Split-ForEach task provides a form of searching or enumeration
over the pages in a property. Use a Split-ForEach shape to iterate over
the pages of a Page List or Page Group property. For each page, you can
conditionally start a flow execution for the work object.
41. Privileges usage…
A privilege is an application-specific access control element associated with a class and access role.
A privilege rule is an instance of a Rule-Access-Privilege rule type.
Using privilege rules in an application is optional, but they can offer finer control over access than access roles alone.
42. Decision / fork usage… Scenarios Decision:
Decision:
Use the Decision task ( ) to reference a map value rule, decision
table rule, decision tree rule or a Boolean expression that when
evaluated produces a value that is the basis of branching in the flow.
At runtime, the system evaluates the decision rule based on inputs
from the flow and the work object, and chooses one of the outgoing
connectors based on the result. No user interaction or input is
required.
Fork: Use the fork shape ( ) to represent a point where the flow execution chooses one of a few different paths (connectors) based on tests on the work object. At runtime, the system evaluates the conditions on each outgoing connector, starting with the connector assigned the highest likelihood
